Highway green laser lights serve as "anti-fatigue laser lights." At night, these lights illuminate to remind drivers to stay alert and avoid drowsy driving. Additionally, they assist in monitoring speeding, illegal use of emergency lanes, accident-prone areas, various violations near ramps, and traffic flow. Below is how anti-fatigue laser lights work: 1. Highways often have straight roads with few fixed reference points, leading to monotonous driving actions and single-line vision. Prolonged driving under such conditions can cause drowsiness, especially in summer when high daytime temperatures deplete energy. Truck drivers frequently undertake long-distance night trips, increasing the risk of fatigue driving, which has become a key focus for highway traffic authorities to prevent and penalize. 2. Laser lights are installed to stimulate drivers through changing light patterns, alleviating visual fatigue caused by uniform driving environments. After multiple on-site inspections and discussions, highway police positioned these lights on relatively straight sections prone to fatigue driving. The lasers are adjusted to ensure sufficient brightness while providing visual impact. They operate in continuous or strobe modes with a range of 2 kilometers. 3. Laser lights are just one of many anti-fatigue measures employed by highway police. Other measures include flashing warning lights and reflective strips. Ultimately, preventing fatigue driving relies more on raising driver awareness and ensuring adequate rest.

How Often Should the Oil in a Dry Dual-Clutch Transmission Be Changed?

Dry dual-clutch transmission oil is typically changed every three years or after driving 60,000 kilometers. The internal structure of a dry dual-clutch transmission is relatively complex, requiring high-quality transmission lubricants. Therefore, it is recommended to use the manufacturer's specialized oil for replacement. Dual-clutch transmissions are divided into dry and wet types. Both types operate on similar principles, with two clutches taking turns to work. However, the connection medium between the clutch's driving and driven plates differs. Dry dual-clutch transmissions rely on air, while wet dual-clutch transmissions use oil. Dry and wet dual-clutch transmissions share similarities but also have distinct differences, each with its own advantages and disadvantages. The primary difference lies in the working environment of their clutch plates. In wet dual-clutch transmissions, the clutch plates are immersed in transmission fluid, whereas in dry dual-clutch transmissions, the clutch plates directly contact the engine flywheel. In terms of technological maturity and reliability, wet dual-clutch transmissions are more stable because the clutch plates operate in hydraulic oil, which provides some cooling effect. Dry dual-clutch transmissions, due to their poor heat dissipation, are prone to overheating of the clutch plates in congested urban areas, posing a risk of burning or erosion.

What Does Energy Recovery in Electric Vehicles Mean?

Energy recovery in electric vehicles literally means: recycling wasted energy and then recharging the power battery with electricity. Function: This can ensure or even increase the battery's driving range. Information about electric vehicles is as follows: Electric vehicle (EV): refers to a vehicle that uses electrical energy as the power source and is driven by an electric motor, belonging to the category of new energy vehicles. Classification: includes Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), and Fuel Cell Electric Vehicles (FCEV). There are mainly two modes of energy recovery in electric vehicles: braking recovery and coasting recovery. The difference between the two lies in whether the brake pedal is pressed. As the name suggests, braking recovery is achieved by pressing the brake pedal, while coasting recovery is achieved by releasing the accelerator to coast. Currently, there are two ways to achieve motor braking energy recovery: one is the Parallel Regenerative Braking System (RBS), and the other is the Series Regenerative Braking System (CRBS). The differences between the two are as follows: In RBS, since the brake pedal and the brake wheel cylinder are parallel, during braking deceleration, the brake wheel cylinder generates hydraulic braking, and the motor also generates braking. Therefore, some energy is still lost through braking friction, resulting in lower energy recovery efficiency. In CRBS, the brake pedal and the hydraulic mechanism are parallel. During braking deceleration, the motor brakes first, acting as the main torque source, while hydraulic braking compensates for insufficient braking torque. Thus, CRBS recovers more energy than RBS, but if the brake is pressed to a certain depth, the two are similar. Regarding vehicle selection: To minimize energy consumption, it is advisable to choose a vehicle with CRBS functionality. Of course, if possible, use coasting energy recovery more often, as coasting energy recovery is 100% free from other external forces, whereas braking energy recovery may involve some low-voltage power consumption during CRBS operation, and hydraulic braking may intervene in certain conditions, causing energy loss. Benefits of kinetic energy recovery: Energy saving: Because it converts part of the vehicle speed into battery power, it relatively saves energy. Saves brake pads: Experienced drivers can reasonably use kinetic energy recovery to decelerate, reducing the number of brake applications, thereby saving brake pads. Improves braking effect: While braking, kinetic energy recovery also works, effectively enhancing the braking effect.

Does the China 6 Civic have a particulate filter?

In the Civic series, China 6A models do not come with a particulate filter, while China 6B models are equipped with one. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they enter the atmosphere. It can reduce soot emissions from diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. How the particulate filter works: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate trap through a dedicated pipe. Inside, a densely arranged bag-type filter captures the carbon particles on a metal fiber mat filter. When the accumulation of particles reaches a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide, which is then expelled. To check whether the China 6 Civic has a particulate filter, you can use the following three methods: 1. Refer to the and to see if the particulate filter function is mentioned. Additionally, carefully check the fault codes in the manual to see if there is a "particulate filter" warning light indicator. 2. Check the label on the oil filler cap. If the cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. 3. Look at the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If present, that is the particulate filter.
